<p>Is it important to ensure my machine is otherwise idle-ish while running the rustc-perf collector locally, if I'm just looking at instruction counts?</p>

<p>I would try to at least keep a few cores idle, but it probably doesn't matter too much. Generally speaking though you're likely to get less noise the less is happening.</p>

<p>Gotcha, thanks :)</p>
